HOPPER-CAR DOOR.

I Application filed September 29.1 925. Serial No. 59, 40sa This invention relates to railway cars of the type more particularly known as dump cars which have drop doors hinged to the 'underframe and extending beneath certain members of the car, and the invention has for its object to improve the construction of such cars by providing means for m nimizing leakage of material therefrom, and for strengthening the doors so as to adapt the cars to meet. the various requirements for successful.commercial operation.

The object of the invention is to stiffen the corner or corners of the door, as any bending or drooping of the'corners would cause a leakotthe lading, especially of such fine material as sand, chats, etc. Any bending orwarping might intertere with the complete closing or locking of the door.

In the drawings:

Fig. 1 shows a l1oppei'. door with my reinforcement having my approved construction.

Fig. 2 is a side elevation of Fig. 1

Fig. 3 is a section on line 33 of Fig. 1. Fig. 4 shows a modified form of my invention. J j n Fig. 5 is a section on'line 55 of Fig. 4..

F ig. 6 is similar to Fig. 3 but shows the embossment projecting upwardly.

The door is made of a metallic plate (preterably steel) haying flanges 23 (preferably continuous) on all of its sides which strengthen the door to carry the lading. Thecorners of the door are stiflened, by an embossment near the adjacent side of the flanges (or bend of a continuous flange) which stiffen the corner of the door against drooping or bending; for instance, on lines parallel to line 6- 6 in Fig. 1 or line 7 in Fig. 4.

In the construction shown in Figs. 1 to 3, inclusive, the embossment comprises two portions 8-9, each adjacent one side of the door, which portions. are widest at their juncture 10 and taper towards their ends l112.

In the modification shown in Figsd and 5 the embossment 13 ispositioned so as, to substantially bisect the angle of the corner ofithe door and is widest (14) adjacent the end 15 nearer to the corner 0 the door, and two of its sides are substantially parallel to the corresponding sides of the door.

The embossments preferably project upwardly but may'bepre sed downwardly and come within the scope of the invention.

Downwardlfy projecting em'bossmen-ts' should be provided with drain holes 16 The embossments may be used in the outer corners only or the inner corners only or in all four corners, if desired.
